Concept: Chrysler EcoVoyager

Not to be confused with the company's long-defunct Plymouth Voyager minivan, the forward-looking Chrysler ecoVoyager is a four-door, four-seat concept car powered by a plug-in lithium ion battery the automaker claims will deliver range of at least 40 miles on a full charge. For longer trips, a hydrogen fuel cell kicks in to charge the batteries, upping range to more than 300 miles. The entire propulsion system is located beneath the car's floor, facilitating the car's unique proportions. Interior highlights include an LCD display that allows the front passenger to watch a movie without distracting the driver.
